Normally TDC can be found on the rotor and on the camshaft sprockets, in some cases though, like my bike. The markings, "F" and "T" were on the reluctor for the ignition pulse generator,

What cylinder you trying to find TDC? you doing valve lash check on it?

lil trick is stick a long toothpick or pencil down the cylinder you are trying to find tdc and turn it until the pencil/toothpick is that the highhest point. do it severval times to be sure this is just around the way to check

i just have to align the 'F' looking though an access hole in the stator cover. That and the F holes in the cam gears need to be in a certian spot. They dont always line up but an extra turn counterclockwise does it.

the pencil trick will give you true tdc.

The pencil method is good but be careful not to break the end off into the cylinder...Then it ALL has to come off

My Honda and Suzuki use the "F" and "T" marks, where "T" is TDC. Good enough for checking valve clearance. If you want to degree your cam with slotted cam sprockets, you will need to use a degree wheel mounted on the crank and a mounted pointer for accuracy.

I have a piston stop, that can be screwed into the sparkplug hole. It is an aluminum stop screw in a steel case that is screwed down into the cylinder. You slowly rotate the crank until the piston stops (hits the stop screw). Check the pointer on the degree wheel (say it points to 40 degrees before TDC). Then rotate the crank the other way until the piston hits the stop (say it points to 60 degrees after TDC). Add the numbers and divide by 2 which gives you 50. Loosen the bolt holding the degree wheel and rotate it 10 degrees until the pointer points to 50 degrees and tighten it. Take out the piston stop and rotate the crank until the pointer points to TDC and it will be. Just make sure it's on the compression stroke.

That almost exactly the same technique to find the LC on your cams (lobe center) mainly done that with hot cams for the old ATC110 that is norm done when new cams are ordered as you get a lil placard stating the LC and thats what you have to set the motor to or baaaaad things will happen if they are off far enough!
